Revolving Live and Dead Centers | Accu-fix Precision Tools
Frequently Asked Questions
1. What is a dead center?
A dead center is a tool used in turning operations to support the one end of the workpiece. It does not rotate and remains stationary while the workpiece turns around it, preventing deflection or bending.
2. What is a revolving (live) center?
A revolving live center is a center with bearings so the tip rotates together with the workpiece. It is mounted in the tailstock and provides smooth support during high-speed operations.
3. What materials are live and dead centers made from?
Dead and live centers are made from hardened steel or HSS for durability and wear resistance. Tips are heat-treated up to 60–64 HRC, and some models include carbide tips for higher precision.
4. When should you use a dead center?
A dead center is used in slow, precise operations where minimal movement is required. It requires lubrication due to friction and is ideal for grinding and fine turning.
5. When is a revolving (live) center used?
A live center is used in high-speed machining to support rotating workpieces. It reduces friction, heat, and wear while improving accuracy and smooth operation.
6. What are signs that a center needs replacement?
Common signs include vibration, unusual noise, excessive heat, or reduced machining accuracy. For more information, contact us at:
